Document Summary

Gas exchange is the uptake of o2 from the environment, and the discharge of co2 to environment. Their final resting place is in combination with o2 to make water. ) Cellular respiration also produces co2 because co2 is one of the product of citric acid cycle. Co2 cannot be allowed simply to accumulate in an animal"s body water. Co2 lowers the ph of the body fluids if it accumulates in them. Diffusion takes place much faster through air than through water. (affected by the constant d) At 12 degree celsius, the air will contain 200 ml of o2 per liter. The water will only contain 7. 7 ml of o2 per liter at 12 degree celsius. The solubility of o2 in water is so low that the amount present per liter is only about 4% of the content is the air-even when the water is steadily bubbled with water.
